is developing a stand-alone camera app to encourage its 1.6 billion users to create, and share, more photos and videos, people familiar with the matter said.

A prototype of the app developed by Facebook’s “friend-sharing” team opens to a camera, similar to disappearing photo app Snapchat, the people said. Another planned feature allows a user recording video through the app to begin live streaming, they added.

The project is in its early stages and may never come to fruition, the people said.

Still, it reflects anxiety within Facebook over users’ increasingly passive behavior on the social network. Many users check Facebook daily or even multiple times a day, but fewer are sharing photos, videos and status updates about their own lives. Reversing the trend is a growing priority within the company.

A Facebook spokeswoman declined to comment on product plans. The spokeswoman said the overall level of sharing on Facebook was strong and “similar to levels in prior years.” The people familiar with the matter said the camera-first format is aimed at motivating users to create photos and videos.

By comparison, Facebook’s flagship mobile app opens to a personalized feed of articles, status updates and ads that encourages users to consume content, but not necessarily create it. The approach also differs from Facebook’s Instagram image-sharing network, which has gained a reputation as a place to post only the best, most well-photographed images. Instagram forces users to go through several steps before posting a picture, including filters. This isn’t the first time Facebook has built an app to encourage sharing.

In June 2014, it launched Slingshot, a Snapchat-like app that let users trade photos and videos that disappeared after 24 hours. It earlier launched a photo-editing and -sharing app called Camera. Neither gained much traction among users and both were later dropped. The new app would have slightly different features, such as the live-streaming “mode.”

The decline in sharing on Facebook has emerged as a problem in the past year.

Technology-news website The Information reported earlier this month that “original broadcast sharing” on Facebook was down 21% as of mid-2015, compared with the prior year. In the first quarter of 2016, 33% of Facebook users polled by market researcher GlobalWebIndex said they updated their profile status in the past month and 37% said they uploaded or shared their own photos. A year ago, 44% said they updated their profile status in the prior month and 46% said they uploaded or shared their photos.

The camera app is just one way Facebook is tackling the issue. The company started to display prompts, or “reminders,” at the top of some users’ news feeds last year. Many prompts are based on a user’s interests and location; others are for holidays such as Father’s Day, football games or television show premieres.

Facebook has also attempted to re-engage users with new features such as “On This Day,” which lets users relive and share past posts. This and similar features appear may have prompted more users to “like” Facebook posts, according to GlobalWebIndex, which said that in the first quarter of 2016, 82% of Facebook users clicked “like” at least once in the prior month, up from 73% during the same period a year earlier.

More recently, Facebook gave some users the option to post pre-made collages from their recently taken photographs. Last month, the company bought video-sharing app MSQRD, which lets users enhance videos through filters and offers the ability to “swap” faces with others in the picture. Snapchat has a similar feature in its main app.

People familiar with the matter said the camera app under consideration is also intended to spur creation. The content could then be shared to Facebook or its other properties, including Instagram.

But any new app will face a challenge among users increasingly reluctant to download more apps. Facebook itself made this argument earlier this month for “chatbots” within its Messenger mobile app. Last year, Facebook shut its in-house app incubator, Creative Labs, and removed three of the unit’s unpopular apps from the Apple’s App Store and Google’s Play store. Facebook said it would continue to develop stand-alone apps.
